12,000,000; and in Prussia, in 1865, 18,000,000 tons were 
produced. The statistics procured at the exposition have 
enabled me to construct the following table of the produc¬ 
tion of iron in the world, in 1866, and there is every reason 
to believe that the figures given are substantially correct, as 
estimates were resorted to only in one or two cases, and 
those based upon former official returns:

Allowing for the production in barbarous countries, and 
something for the use of scrap iron, it may be stated in round 
numbers that the production and consequently the consumption 
of the world has reached 10,500,000 tons, of 2,240 pounds each, 
or 21,280 millions of pounds ; so that if the population of the 
world has reached 1,000 million, a consumption of a little 
over twenty pounds of iron per head. A careful calculation, 
after allowing for iron exported, shows that the consumption 
per head in England is 189 pounds of iron. The consump¬ 
tion in Belgium has reached about the same limit. The con-
